It would be interesting to know how to move up and down the list and if your 'rating' varies by property.
At one of my favourite Hyatt's I made a relatively small complaint (about being told that my Amex FHR amenity was 2 pieces of fruit and not the one they usually give out) and at my next stay I approached the check-in and the lady seemed to be incredibly nervous. She said that the GM had said I was arriving, upgraded me to a suite and took me upto the room for check-in. So there must be something in this list. Next stay was a few weeks later at a different Hyatt and the service was standard so maybe it is property related?
